Digit.

Traditional sentence-level approaches are susceptible to linguistic variability, limiting their ability to extract disease-specific acoustic features and reducing overall robustness. This study presents a vowel-based intelligent recognition framework for T2DM (VDT2) designed to capture stable and discriminative pathological speech features. The framework combines Lasso regression with recursive feature elimination to identify the most relevant acoustic indicators, and applies a dynamic logistic regression ensemble enhanced with an attention mechanism to strengthen feature representation. Experiments conducted on a self-constructed speech dataset demonstrate that VDT2 achieves a detection accuracy of 78%, outperforming conventional sentence-level methods. These findings highlight the potential of vowel-based analysis as a robust and non-invasive tool for T2DM detection.<\/jats:p>","DOI":"10.3389\/fdgth.2026.1739091","type":"journal-article","created":{"date-parts":[[2026,5,18]],"date-time":"2026-05-18T05:43:01Z","timestamp":1779082981000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Study
